The so called "benign" central serous retinopathy is associated in healed forms with frequent and troublesome visual function impairment. The abnormalities are still more severe after diffuse retinal pigment epitheliopathy. Snellen visual testing is relatively imprecise index of visual function, so it does not permit to appreciate the subtle visual disturbances experienced by these patients. We evaluated visual function disability with static automatized perimetry and contrast sensitivity in 30 patients with diffuse epitheliopathy in a cicatricial phase. Colour vision was also evaluated by 16 patients after central serous retinopathy. The results of this study are examined and discussed.
